2023-02-10by admin

  price trend

  according to the monitoring of sunsirs, the market of fluorine chemical industry was sluggish after the holiday, and the products fell more and rose less, the price trend of raw materials and products fell back, the overall trend of nstream products was not ideal, the operating rate of refrigerant industry was not high, the nstream demand was poor, and the market of fluorine chemical industry was sluggish.

  analysis review

  fluorite: as a raw material for the fluorine chemical industry, the price of fluorite had fallen from a high level, the intra-field fluorite trading was weak, the operating rate of fluorite enterprises was not high after the holiday, and the supply of fluorite had decreased. in addition, mining enterprises were facing increasingly stringent requirements for safety and environmental protection, resulting in insufficient commencement of fluorite mines. although the supply of fluorite had decreased, the nstream enterprises had sufficient stock before the festival, and the procurement was scarce. the price trend of fluorite on the market had declined.

  hydrofluoric acid: the price of domestic hydrofluoric acid dropped sharply. as of the 7th, the mainstream negotiated price of domestic hydrofluoric acid in various regions was 9,800-10,300 rmb/ton. some units were still in shutn recently, but the spot supply of hydrofluoric acid was sufficient, and the manufacturer’s hydrofluoric acid orders were poor, which affected the price trend of hydrofluoric acid nward. in addition, the price of raw fluorite had fallen, and the decline of sulfuric acid market had not decreased, which had brought some negative impact on the hydrofluoric acid market. the hydrofluoric acid market price was under nward pressure.

  aluminum fluoride: the average price of domestic aluminum fluoride was 11,075 rmb/ton. the price trend after the holiday had declined. the contradiction between supply and demand of aluminum fluoride was acute, and the capacity was seriously excessive. in addition, the trend of raw material market had declined, and the cost had fallen, resulting in the continuous decline of aluminum fluoride market price. after the holiday, the demand for aluminum ingots remained weak, the price of electrolytic aluminum fluctuated and fell, the demand for aluminum fluoride was weak, and the nward pressure on aluminum fluoride was increased.

  refrigerant: the market of nstream refrigerant products was low, and the operating rate of the refrigerant industry remained low. after the spring festival, some enterprises resumed work and raised the factory price slightly, driving the domestic refrigerant r22 price to rise slightly. the lower price of hydrofluoric acid had put pressure on the refrigerant industry. the refrigerant r22 manufacturer’s load was not high, the inventory was in a reasonable range, and there was a lot of wait-and-see mood. the shipment situation of the holder was normal, and the r22 price increase was limited. the domestic r134a manufacturers operated at low load, and the price trend of r134a remained stable. however, the procurement was mainly based on demand, and the nstream enterprises did not start high. the traders were in a strong wait-and-see mood. the market price of refrigerant r134a was mostly in the range of 24,000-25,000 rmb/ton. affected by the fact that some enterprises had not yet resumed production, the relatively low inventory of enterprises and the light refrigerant delivery and trading after the spring festival, the nstream r134a market was depressed.

  market outlook

  after the holiday, the fluorine chemical industry had a poor trend, the demand of the refrigerant industry had not improved, the aluminum fluoride industry had a sharp decline, and the prices of raw materials fluorite and hydrofluoric acid had a nward trend. the fluorine chemical industry was under pressure. on the whole, the negative factors dominated the market. it is expected that the market rebound pressure will be large in the later period, and the whole industry may maintain a weaker trend.
